Hello,

I did all the steps from the Hartl tutorial but as soon as I do this :

User.create(name: “Michael Hartl”, email: “mhartl@example.com”,password: “foobar”, password_confirmation: “foobar”)

on the rails console, I see this error message :

Hello,

I did all the steps from the Hartl tutorial but as soon as I do this :

  User.create(name: "Michael Hartl", email: "mhartl@example.com",password: "foobar", password_confirmation: "foobar")

on the rails console, I see this error message :

Make sure that your Gemfile looks EXACTLY the same as Señor Hartl's. I am betting you are missing the bcrypt library. (It's commented out in a default `rails new` generated site.

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

Walter

#3

I have exactly what Hartl says.

He says to change my gem file to this :

source 'https://rubygems.org'

gem 'rails',                '4.2.0.rc1'
gem 'bcrypt',               '3.1.7'

And there is no mention about bcrypt-rubt

Roelof

#4

Also did you create the password_digest field in the database as in
listing 6.32 and run db:migrate? Check in db/schema.rb to see if that
field exists, and make sure it is spelled correctly.

Colin

#5

It may have been renamed since the example I looked at. I haven't used 4.2 yet. (Okay, just checked, and it is the way you describe -- same version, even -- in 4.1. Sorry for the noise.)

Walter

#6

Did you run bundle install after that? It does not look as if you are
using 4.2.0.rc1.

And please don't top post, it makes it difficult to follow the thread. Thanks.

Colin

#7

Yep, I did all the steps.

Here is my scheme.rb file :

encoding: UTF-8

This file is auto-generated from the current state of the database. Instead

of editing this file, please use the migrations feature of Active Record to

incrementally modify your database, and then regenerate this schema definition.

#8

Yep, I did all the steps.

Though have not responded to my request that you do not top post. :frowning:

So your Gemfile is exactly the same as in the tutorial? If you think
so then please post it here, along with Gemfile.lock

Colin.

Though have not responded to my request that you do not top post. :frowning:

Here my gem file :

Are you following
https://www.railstutorial.org/book/modeling_users#sec-creating_and_authenticating_a_user?
Listing 6.33 shows a different version of Rails (as I have already
pointed out). Please check that your Gemfile is /exactly/ the same as
in the tutorial, then run bundle update. There is no guarantee that
is the issue but you must rule it out first.

#11

You are right. The version changed in the time that I follow that tutorial.

I now facing this problem :

Bundler could not find compatible versions for gem “arel”:
In Gemfile:
rails (= 4.2.0.rc1) ruby depends on
activerecord (= 4.2.0.rc1) ruby depends on
arel (~> 6.0) ruby

arel (6.0.0.beta2)

Roelof

Edit 1 : I can delete the arel version but then I will run into this problem : https://groups.google.com/forum/#!topic/rubyonrails-talk/9KY84ScB_6A

I am also learning now…Have you tried “has_secure_password” in the User model.
